Re: difference between mom_contact_normal and mom_contact_vector
I couldn't find anything either. Maybe GTAC can ask development for you. When you find out let us know here. My guess is Normal has to do with a surface, and Vector has to do with the tool/tool tip? I am just speculating though based on verbage used in other areas of NX.
